The one that is blocked is very favorable.
But besides that, none of them are overtly negative either. I think the bad reviews posted on this site have kind of blossomed and left a sour taste in everyone's mouth meaning the ride will now always have a bad stigma associated with it by any user of this site who has read it get blasted. I'm sure that if the first reviews on here had been more positive, the succeeding reviews would have been a lot more forgiving. And I've noticed this sort of group think happen before--people were ripping on the idea of Transformers coming to Universal before it was confirmed, and now everyone is super excited for it because the mood of the board changed.
I'm not saying it's the greatest ride ever, but even from only seeing the video it seems like it's getting really ripped apart for nothing. Compared to the rest of SeaWorld's attraction lineup, I'd say it's pretty well-done. And from what I understand, the ride is really not the main attraction, it's a unique way of entering the exhibit, and in that regard it actually succeeds.
